1,4,5,6,7,7-hexaphenyl-7-sila-bicyclo[2.2.1]hepta-2,5-diene-2,3-dicarboxylic acid dimethyl ester is a complex organic compound with a unique molecular structure. It features a bicyclo[2.2.1]hepta-2,5-diene core, which is a seven-membered ring with two carbon atoms and one silicon atom. The silicon atom is located at the 7-position, and the molecule is adorned with six phenyl groups, one at each of the 1, 4, 5, 6, and 7 positions, with the 7-position phenyl group being counted twice due to its connection to the silicon atom. The molecule also contains two carboxylic acid groups at the 2 and 3 positions, which are esterified with methanol to form dimethyl esters. 1,4,5,6,7,7-hexaphenyl-7-sila-bicyclo[2.2.1]hepta-2,5-diene-2,3-dicarboxylic acid dimethyl ester is characterized by its large, rigid structure and potential applications in materials science and organic chemistry, particularly in the study of sila-analogues of organic compounds and their unique properties.
The CAS Registry Mumber 1184-27-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,8 and 4 respectively; the second part has 2 digits, 2 and 7 respectively. Calculate Digit Verification of CAS Registry Number 1184-27: (6*1)+(5*1)+(4*8)+(3*4)+(2*2)+(1*7)=66 66 % 10 = 6 So 1184-27-6 is a valid CAS Registry Number.
